Comment 3 for bug 592418

Four more definitions I found quite useful:

    <marker style="overflow:visible" id="SharpMstart" refX="0.0" refY="0.0" orient="auto" inkscape:stockid="SharpMstart">
      <path transform="scale(0.6, 1) translate(0,0)" d="M -10,0 C -7.8,-0.31 -3.4,-0.45 0.01,-0.5 L 0.01,0.5 C -3.4,0.45 -7.8,0.31 -10,0 z " style="fill-rule:evenodd;stroke-width:0.62500000;stroke-linejoin:miter"/>
    </marker>
    <marker style="overflow:visible;" id="SharpMend" refX="0.0" refY="0.0" orient="auto" inkscape:stockid="SharpMend">
      <path transform="scale(0.6, 1) rotate(180) translate(0,0)" d="M -10,0 C -7.8,-0.31 -3.4,-0.45 0.01,-0.5 L 0.01,0.5 C -3.4,0.45 -7.8,0.31 -10,0 z " style="fill-rule:evenodd;stroke-width:0.62500000;stroke-linejoin:miter;"/>
